The subcarrier of PUSCH transmission is supported under such as single tone, it is assumed that subcarrier width is 3.75KHz, on frequency domain One has 12 × 4=48 subcarrier, it is necessary to 6bit instructions can be indicated in DCI.In order to reduce the expense of resource allocation, can Can be used for the total number of sub-carriers of transmission information with using high-level signaling configuration, such as by 8 sons of 3.75KHz of bandwidth both sides Carrier wave is allocated to UE, then can be indicated to the subcarrier that UE is distributed with 3bit.Numeral index can according to frequency increase or The order of reduction, or according to from both sides successively to the order at center.In order to reduce waste, the subcarrier and system of 3.75KHz In the subcarrier of 15KHz should have protection band, such as protection band is 1 or 2 subcarrier of 3.75KHz.Another kind is matched somebody with somebody The mode of putting is the subcarrier that eNB can configure several 15KHz to UE, due to 12 subcarriers can be included in system altogether, therefore Can be represented with 4bit.UE according to configuration 15KHz sub-carrier positions, using the region of each 15KHz as 4 3.75KHz Subcarrier be transmitted, and several subcarriers of the marginal position of configuration are interpreted as protection band, when the resource of UE transmission is During implicit mapping, should be mapped on the subcarrier outside protection band.Such as assume up all subcarriers from frequency it is minimum to Highest number consecutively be 0,1 ... 11, eNB to UE distribution 15KHz subcarrier #0 and #1 as the 3.75KHz of UE transmission Scope, corresponds to altogether 8 subcarriers of 3.75KHz, and the son of the two subcarrier #2 that it neutralizes 15KHz adjacent 3.75KHz is carried Ripple is used as protection band, and other 6 subcarriers of 3.75KHz are used to transmit, during for implicit mapping, transmission it is total The sub-carrier number of 3.75KHz is 6, and mapping equation should be substituted into 6 and calculated.Preferably, the 3.75KHz that eNB is configured to UE Transmission range should try one's best and concentrate on bandwidth side, so reduce the frequency band that protection band takes.Such as eNB to UE dividing frequencies most Two low subcarriers of 15KHz as the 3.75KHz of UE transmission range.Two subcarriers of 3.75KHz of frequency highest It is protection band.

2) time-domain resource：

When time-domain resource includes domain scheduling granularity and time domain distribution when domain scheduling granularity number.When domain scheduling granularity can To be default, such as domain scheduling granularity is that 48 subframes, or eNB notify that such as eNB is selected from a set when Select one to notify to UE, can be notified with RRC signaling or SIB or DCI, the set is that eNB is notified, such as pass through What RRC signaling or SIB were notified, or it is default.Time domain distribution when domain scheduling granularity number can be it is default, than Such as it is 8, or can is that eNB is notified, can be notified with RRC signaling or SIB or DCI.

Time-domain resource can also be obtained using default mode, such as give a code check, or according to covering grade And/or operative scenario one code check of correspondence, time-domain resource is calculated according to TBS sizes, code check can be it is default, such as 1/3, or be eNB configurations.

3) number of repetition：

Can be indicated by DCI or RRC, or obtained according to covering grade and/or operative scenario are implicit.

Combined coding can also be carried out to the information of above-mentioned needs configuration, reduce the bit numbers of resource allocation.

Or, above- mentioned information can have default corresponding relation, and then can reduce the bit numbers of instruction.Such as, MCS and Time-domain resource granularity has default corresponding relation, such as MCS is bigger, and time-domain resource granularity is bigger.Or TBS and time-domain resource grain Degree has default corresponding relation, and TBS is bigger, and time-domain resource granularity is bigger, such as when TBS is less than a thresholding, time-domain resource grain It is 48 subframes to spend, and is otherwise 96 subframes.So, different time domain resource can be indicated using identical bit numbers.

Alternatively, the different when domain scheduling granularity/number of repetition of different sub-carrier positions correspondences.Such as assume From 0 numbering since frequency is minimum, the correspondence number of repetition of subcarrier 0~3 is 4, the correspondence of subcarrier 4~7 to the subcarrier of 3.75KHz The specific sub-carrier indices of number of repetition 8. can be indicated in DCI.When the number of repetition that eNB distributes to UE is 4, then eNB What the DCI in the scheduling authorization sent to UE was indicated is a subcarrier in subcarrier 0~3.

Alternatively, the subframe/CCE where the Downlink Control Information of scheduling PUSCH/PDSCH and the subcarrier for distributing to UE There is default corresponding relation, such as, when last subframe where Downlink Control Information is even number, then correspond to subcarrier 0 ~3, otherwise corresponding to the specific sub-carrier indices of subcarrier 4~7. can indicate in DCI.

Alternatively, PRACH resources and the subcarrier where Msg3 have default corresponding relation, such as the son where PRACH Carrier wave is odd subcarriers, then correspond to subcarrier 0~3, and otherwise corresponding to subcarrier 4~7. specific sub-carrier indices can be Indicated in uplink authorization in RAR.Further, the subcarrier where the Msg3 can also have with the subframe where PRACH Corresponding relation.

Preferred embodiment nine：

In the proprietary SRS of cell, the action of UE includes one below：

Continue to send the symbol, because single tone scenes are generally used under coverage enhancement pattern, signal compares It is weak, therefore the influence for continuing to send to the SRS of legacy UE is little.

Or, destroy the symbol overlapped with the proprietary SRS of the cell, such as one symbol has part and SRS There is overlap, then abandon sending the symbol.

Or, for the symbol overlapped with the proprietary SRS of the cell, destroy the portion overlapped with SRS in symbol Point, remainder still sends.

Preferred embodiment ten：

Such as UE receives PDSCH in subframe #n, needs to send PUSCH in subframe #n+1, then final stage times of the UE in subframe #n Do not receive signal.Or, UE using after descending sub frame close to sub-frame of uplink a period of time for most starting as protection interval. Such as UE receives PDSCH in subframe #n, needs to send PUSCH in subframe #n+1, then UE most starting on subframe #n+1 A period of time not sending signal.Further, the original position that UE sends PUSCH can be first son after subframe #n+1 Frame, or to meet the subframe of N/2 × m or N × m, wherein m is positive integer.

When UE need from transmission be converted into receive when, UE by after sub-frame of uplink close to descending sub frame most start one The section time, in protection interval, UE did not received downstream signal as protection interval (guard period).Such as UE is in subframe #n PUSCH is sent, needs to receive PDSCH in subframe #n+1, then UE does not receive letter in a period of time for most starting of subframe #n+1 Number.Or, UE using before descending sub frame close to sub-frame of uplink the final stage time as protection interval.Such as UE is in son Frame #n sends PUSCH, needs to receive PDSCH in subframe #n+1, then final stage times of the UE on subframe #n does not send letter Number.
